ABSTRACT:
Continuous filaments are fed by aspiration into a stream of heated fluid. The filaments are then contacted with at least a second stream of heated fluid to increase the temperature of the filaments. The combined streams of fluid containing the filaments are directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments. A major portion of the fluid is separated from the filaments and expelled from the chamber. The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the filaments, whereby the filaments are forced against a mass thereof producing crimps therein. One or more streams of heated fluid are then contacted with the mass of filaments to set the crimps. The crimped filaments emerge from the chamber through an outlet opening therein.
